I have been doing a lot of testing lately with a couple of USB based Video Capture adapters with VSX9 and I use three monitors.My Primary Display loads the VSX9 software. The Secondary Display loads a detached Preview Window.

Every time I load VSX9 I see the splash screen on my Primary Display and the Secondary Display starts to show the detached Preview Window but as soon as the loading of VSX9 is completed, I get a Welcome Screen hyping a VideoStudio Ultimate 2019 upgrade offer. My detached Preview Window gets reattached to the main program and I have to detach the window and resize it all over again. This happens every time!
